Hello,
I have a 91 GT Automatic. The check engine light seems to come on after warmup during deceleration.
I have codes 41 & 91 in continuous memory and during KOER.
I have replaced both HEGO's, cannot find a vaccuum leak, checked EGR function and am now out of ideas.
Any help is greatly appreciated.
Thanks

assuming no idle problems, esp on A/C switching on and off.... then check the air injection system.
i'd think it would shut down injection on deceleration.
